Animates a 144 LED Adafruit DotStar strip using the pyo library to pick up and change a voice to sound kinda robotic.
Tested with a C-Media external USB sound card on a rpi4.
Plug in DotStar pins:
- Yellow: GPIO11 (
SCLK) - clock - Green: GPIO10 (MOSI) - data
- Black: GND
DotStar gets its power using 5v a micro USB.
- Micro USB pinboard
- 1000µF (6.3V or higher) capacitor close to the strip (between 5V and GND wires) to handle inrush curent.
